-[GKPlayerInternal setAuthenticateHandler:]: unrecognized selector sent to instance

Question

Get error SIGABRT with this log: "-[GKPlayerInternal setAuthenticateHandler:]: unrecognized selector sent to instance"

I test this on iPad 3 iOS 5.1.1

GKLocalPlayer* localPlayer = [GKLocalPlayer localPlayer];
localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error)  //error here
{ /* some code */ };

On iOS 6 this work fine

Answer 1

I'm glad you mentioned you're trying this with iOS 5.

According to Apple's documentation, "authenticateHandler" is iOS 6 and newer only.
